Getch input

[Walker]

okay im using a keyboard for input and my code is

code:

if hasch then         getch (key)     end if     if key = ("w") then         yy := yy + 20     elsif chars ("s") then         yy := yy - 20     elsif chars ("d") then         xx := xx + 20     elsif chars ("a") then         xx := xx - 20

i would ecpect this to move the xx and yy values up and down by using the w,s,a and d keys but instead is does nothing. What did i do wrong?

How about you get rid of the if hasch part. It seems redundant to me.

code:

loop getch (key) if key = "w" then %... end if end loop

I'm not entirely sure what your "+ 20" thing was all about...I can only imagine that it has something to do with your locates? Well, that is if you are using ASCII art.
Otherwise, it probably has something to do with your xy-coords? I'm just guessing...

you switch from asking "is key = to whatever character" to "is chars = to whatever character".

if you are using this for a game, read up on Input.KeyDown()

code:

var key : string (1) var x, y : int := 0 loop     if hasch then         getch (key)         if key = ("w") then             y += 10         elsif key = ("s") then             y -= 10         elsif key = ("d") then             x += 10         elsif key = ("a") then             x -= 10         end if     end if     drawfillbox (x, y, x + 10, y + 10, black) end loop
